rajab natshahThank you Durum for reporting,
Have you had a run for "drush updb" or "/update.php" before you try to do the optional updates?
Have you had a look at Handling Configuration Updates ?
Please, have a backup for the site, and do the test update on a local development environment.
It's very important to restore your database if you are testing the update for number of times.
And not to run the optional update twice on the same database

durum commentedThank you for the answer.
Yes, several times. Just to be sure it tells me that there are no pending updates.
Read the documentation several times. Went through the code before running the updates. Also before doing the update, I saw that
$optional_install_pathwasn't declared. I thought "maybe it is something with php 7 and Drupal 8. And maybe it is declared somewhere else as a constant that I can't be sure of right now". Then I run the update. Snippet below.$optional_install_pathnot declared.I am on local dev. Not staged yet.
I did run first time and got the folowing output. Then I run it with
--forceand got the second following output.### Here I run the 8702 and 8703. Similar outputs. Then I forced 8703;
These are not related to the OP but providing info since you asked.
Thanks :)

rajab natshahThank you Durum again for following more on the issue :)
I confirm the issue
Moving the issue to Varbase Core
This should be a Quick fix with a Quick fix release

bgprior commentedMinor version upgrade (7.4.0) of varbase_update_helper has allowed upgrade of varbase_core to 7.4 for me. Thanks.
